Clinical Trial Summary

Background: As many as 1.5 million Americans are living with systemic lupus erythematosus (Lupus). Lupus makes people very tired. It also makes it hard for people to be physically active. Studies have shown that aerobic exercise training helps people with heart or lung illnesses be less tired and more active. Researchers want to use an exercise training program on people with Lupus to see if it has the same results. Objectives: To find out if aerobic exercise helps people with Lupus be less tired and more active. Eligibility: Women ages 21-80 who have Lupus and are not physically active. Design: Participants will be screened with a medical history and physical exam. They will have heart and lung tests, as well as blood and urine tests. They will also answer questions about their quality of life and take a test that measures lupus activity. The study will last 14-16 weeks. For the first two study visits, participants will do treadmill exercise tests and answer more quality of life questions. For these treadmill tests, participants will wear sensors, a mask, or a mouthpiece while they exercise. Participants will then begin exercise training, 3 times a week for 12 weeks. At each of these visits, they will walk very fast for 30 minutes on a track or a treadmill. Each visit will last about 1 hour. At the halfway point of the study, participants will repeat some of the screening tests. This visit will last about 3 hours. At the end of the study, participants will repeat the screening tests. They will also repeat the treadmill exercise tests.


Description:

We propose a single-arm exploratory study to characterize the responses and adaptations to aerobic exercise in women who have mild to moderate systemic lupus erythematosus (SLE) uncomplicated by organ damage that would limit participation. This is a pilot study to provide additional preliminary data to support a future U01 application. Persistent, excessive fatigue is among the three most debilitating symptoms of SLE and is cited by as many as 50% of patients as the single most debilitating symptom. We have observed, in women with mild SLE, significant relationships among deficits in work capacity and oxygen consumption obtained during treadmill exercise and patient reported measures of fatigue severity. Clinically significant functional aerobic impairment was present in these women, suggesting an underlying pathophysiological limitation that restricted cardiorespiratory capacity to well below that expected to occur as a result of normal deconditioning due to a sedentary lifestyle and lack of physical activity. We have also observed prolonged rest to steady state metabolic transition during even submaximal exercise in women with SLE . At peak exercise, muscle oxygenation deficiency was apparent despite normal increases in central circulatory oxygen delivery to the active muscles. Muscle tissue studies in other laboratories have implicated muscle basal lamina thickening as an oxygen diffusion barrier, which could possibly diminish the rate of tissue oxygen uptake and restrict cardiorespiratory capacity. Aerobic exercise training could improve cardiorespiratory capacity in women with SLE and with that improvement precipitate a reduction in their fatigability, particularly if that fatigability is mediated by impaired cardiorespiratory function. Our research team is uniquely qualified to undertake this research and is one of the few teams possessing the experience and background necessary for contributing to this novel, understudied, yet critical field of rehabilitation research. For example, in addition to Dr. Keyser's studies on cardiorespiratory dysfunction in women with SLE, our team has studied the effects of an intense aerobic exercise-training program in individuals who have pulmonary hypertension (PH) or interstitial lung disease (ILD), two conditions associated with autoimmune diseases such as SLE. In fact, several of the subjects had SLE and the majority had autoimmune diseases of somewhat similar etiology. Our results demonstrated improved cardiorespiratory function and diminished fatigability in these patients, without serious adverse events, following a 10-week regimen of intense aerobic exercise training. Adherence to the protocol was over 90% in both subject subsets and there were no serious adverse events in either of these groups. Subjects of the proposed research will be between 21 and 80 years of age and living within a reasonable travel distance from the greater Washington D.C. area. Subjects will be recruited from the NIH/National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) Intramural Research Program (IRP) Lupus Clinics. All tests and exercise training will be conducted at the NIH Clinical Center. There will be a single treatment condition consisting of 12-weeks of supervised treadmill walking, three times a week, for 30 minutes per session, at an intensity of 70-80% of the subject's heart rate reserve. The primary outcome measure for our trial will be the time taken to attain the anaerobic threshold, which is a performance marker of fatigability that is unaffected by patient motivation or perception. Secondary outcome variables will include other measures of cardiorespiratory capacity measured during a cardiopulmonary exercise test (CPET) with accompanying pulmonary gas exchange, central circulatory function (including heart function and an optional measures of peripheral blood flow), and muscle oxygenation analyses. A number of questionnaires will also be completed including: Fatigue Severity Scale, Patient Reported Outcomes Measurement Information System (PROMIS). All of these data will be obtained before and after aerobic exercise training. Study Impact: Aerobic exercise is generally safe, inexpensive, and can easily be made available and accessible to almost everyone. It requires no approval by regulatory agencies and is thus available as a medically prescribed and supervised intervention almost immediately following confirmation of its safety and efficacy. Effective use of aerobic exercise training as a cardiorespiratory, rehabilitative intervention could have a high degree of impact on personal and public health outcomes.

Outcome

Type Measure Description Time frame Safety issue
Primary Change in the Time Taken to Attain the Anaerobic Threshold (AT) The anaerobic threshold (AT) is an objective measure of fatigability, and is determined from gas exchange variables during a cardiopulmonary exercise test (CPET). The effect of exercise training was examined by the change in the time taken to attain the AT by measuring the post-exercise training value minus the pre-exercise training value. A positive value indicates improvement in fatigability and a negative value indicates no improvement or worsening in fatigability. CPET measurement was done once before the start of the 12-week exercise program (pre) and repeated at the end of the 12-week exercise program (post). Before 12-week intervention (Pre) and after 12-week intervention (Post)
Primary Change in the Time Constant for Oxygen Uptake Kinetics The oxygen uptake kinetics is an objective measure of fatigability, determined from oxygen uptake measures during a square-wave exercise test. The time constant is the time taken to reach 63% of the steady state response. The effect of exercise training was examined by the change in the time constant by measuring the post-exercise training value minus the pre-exercise training value. A negative value indicates improvement in fatigability and a positive value indicates no improvement or worsening in fatigability. The square-wave exercise test was done before the start of the 12-week exercise program (pre) and repeated at the end of the 12-week exercise program (post). Before 12-week intervention (Pre) and after 12-week intervention (Post)
Primary Change in Performance Fatigability Index (PerfFI) The performance fatigability index (PerfFI) is a measure of fatigability. The PerfFI was determined during a 10-minute walk test (10MWT). The average velocity of 10MWT was divided by the average velocity achieved over the first 2.5 minutes (decline in performance), then further divided by the total distance walked on the 10MWT (an index of intensity) multiplied by 1000. The effect of exercise training was examined by the change in the PerfFI by measuring the post-exercise training value minus the pre-exercise training value. A negative value indicates improvement in fatigability and a positive value indicates no improvement or worsening in fatigability. The 10MWT measurement was done once before the start of the 12-week exercise program (pre) and repeated at the end of the 12-week exercise program (post). Before 12-week intervention (Pre) and after 12-week intervention (Post)
Primary Change in Perceived Fatigability Index (PercFI) The perceived fatigability index (PercFI) is a measure of fatigability. The PercFI was determined during a 10-minute walk test (10MWT) by rating their perceive tiredness on a 7-point Likert scale after the test. The score is divided by the total distance walked on the 10MWT, multiplied by 1000. The effect of exercise training was examined by the change in the PerfFI by measuring the post-exercise training value minus the pre-exercise training value. A negative value indicates improvement in fatigability and a positive value indicates no improvement or worsening in fatigability. The 10MWT measurement was done once before the start of the 12-week exercise program (pre) and repeated at the end of the 12-week exercise program (post). Before 12-week intervention (Pre) and after 12-week intervention (Post)
Secondary Change in Muscle Oxygenation Muscle oxygenation is indicated by tissue saturation index (TSI), which is the amount of oxygenated hemoglobin divided by total hemoglobin in percent. This is evaluated using near-infrared spectroscopy (NIRS) during the cardiopulmonary exercise test (CPET). Peak TSI is determined at the end of the CPET representing the lowest muscle oxygenation during volitional exercise. The effect of exercise training was examined by the change in peak TSI by measuring the post-exercise training value minus the pre-exercise training value. A negative value may indicate better muscle oxygenation capacity and a positive value may indicate no change or reduction in muscle oxygenation capacity. The CPET was performed before the start of the 12-week exercise program (pre) and repeated at the end of the 12-week exercise program (post). Before 12-week intervention (Pre) and after 12-week intervention (Post)
Secondary Change in Cardiac Function Cardiac function is indicated by cardiac output, which is the amount of blood the heart pumps in 1 minute. It is defined mathematically as the product of the heart rate and cardiac stroke volume. This is measured using bioimpedance cardiography (a non-invasive method of capturing cardiodynamic variables) during the cardiopulmonary exercise test (CPET). Peak cardiac output is determined at the end of the CPET representing the highest cardiac output during volitional exercise. The effect of exercise training was examined by the change in peak cardiac output by measuring the post-exercise training value minus the pre-exercise training value. A positive value indicates improvement in cardiac function and a negative value indicates no change or worsening in cardiac function. The CPET was performed before the start of the 12-week exercise program (pre) and repeated at the end of the 12-week exercise program (post). Before 12-week intervention (Pre) and after 12-week intervention (Post)
Secondary Change in Fatigue Severity Scale (FSS) The Fatigue Severity Scale (FSS) is a 9-item questionnaire that assesses fatigue severity on a 7-point Likert scale. The FSS score is an average of the total score for the 9-items, with a minimum of 1 and a maximum of 7. A higher FSS score indicate more fatigue severity. The effect of exercise training was examined by the change in FSS average scores by measuring the post-exercise training value minus the pre-exercise training value. A negative value indicates improvement in fatigue severity and a positive value indicates no improvement or worsening in fatigue severity.
